Why Technical Debt Kills Migrations

A veteran engineer argues that technical debt is a business risk, not just a developer complaint. Drawing from Dave Farley's work, the piece explains that 'Bit Rot' is a symptom of neglect. When teams lift-and-shift legacy Java monoliths to AWS without refactoring, they simply create expensive, fragile infrastructure that is paralyzed by its own mess.

Beyond messy code, 'Configuration Debt' is the new enemy. Manual AWS Console clicks and unsynced Terraform states create ticking time bombs that can crash entire environments. The article also warns that generative AI tools can become 'High-Speed Debt Generators,' automating the creation of legacy code if developers don't ruthlessly review every line.

The solution requires discipline: refactor constantly, codify infrastructure, and treat untested code as a liability. Without a reliable test suite, teams become afraid to change code, which accelerates the rot. We are paid to solve problems, not automate the creation of future headaches for the next team.
